Widgets in bp-social theme

Hello everyone!
I have just installed bp-social theme. I found a bug in widgets section.. I would like someone to let me know how to get rid of this..
The thing is, I placed all "bp-social" based widgets in sections such as home-left, home-center and home-right. Those widgets are not movable now! I mean, I can't remove or drag-and-drop the same into other sections; whereas, I can able to move other common widgets without any hassle..

Please help me ASAP..
